Problems solved by technology

The operation of wireless access networks for enabling wireless communication is highly energy consuming.
These models have intrinsic inaccuracy when compared to the real-life situation due to modelling errors and simplifications.
This can be a rather demanding task, especially in case of self-optimizing radio access networks that dynam

DETAILED DESCRIPTION OF THE DRAWINGS

[0041]FIG. 1A is a schematic illustration of base stations BS A-BS G providing a plurality of active cells. Each base station location comprises three sectors, thus covering an area around the base station location. For example, cell A1 of base station location BS A serves its best server area marked ‘a1’. Similarly, cells A2 and A3 (not shown) of the same base station location BS A serve their best server area marked ‘a2’ and ‘a3’ respectively. A same set-up is shown for the other base station locations BS B to BS G. In FIG. 1A, the regular pattern of base stations and sectors leads to the commonly known hexagonal of coverage areas.

[0042]At some point in time, cell A1 of base station BS A may experience a low load of active user devices. In such a situation, it may be profitable for energy consumption reduction or other reasons to deactivate, e.g. to completely switch off, cell A1 or even all cells A1-A3 at this base station (illustrated by the w...

Abstract

The invention relates to a method for deactivation of at least one first cell of a plurality of cells in a telecommunications network. User devices in the at least one first cell are triggered to report measurement information regarding one or more second cells of the plurality of cells to the telecommunications network. The measurement information is received in the telecommunications network (preferably using the still active at least one first cell) and analysed (in the telecommunications network or by an external system), in order to determine whether one or more user devices in the at least one first cell are eligible for being served by a second cell of the one or more second cells when the at least one first cell would be deactivated. When the one or more user devices are determined to be eligible for being served by the second cell of the one or more second cells, the one or more user devices are transferred, i.e. are handed over or perform cell reselection from the first cell to the second cell and the at least one first cell is deactivated.

Description

FIELD OF THE INVENTION[0001]The invention relates to the field of telecommunications infrastructures. More specifically, the invention relates to the fields of controlling energy consumption, particularly reducing energy consumption, or electromagnetic radiation, in telecommunications infrastructures comprising wireless access networks.BACKGROUND OF THE INVENTION[0002]The operation of wireless access networks for enabling wireless communication is highly energy consuming. In view of current environmental concerns, increased attention is paid recently to the energy consumption of telecommunications networks.[0003]Various studies have been performed to reduce conventional energy consumption in wireless access networks, e.g. by exploring the option of using sustainable energy sources (Ericsson AB White Paper “Sustainable energy use in mobile communications”, June 2007).[0004]With the development of the 3GGP Long Term Evolution (LTE) network, energy saving for the network is also approa...
